I have written the following code which displays a moving
series of data in a couple of charts. It works, but
there is a lot of flashing and flickering while it is
running. Can someone tell me how to eliminate the screen
flashing??

Sub xdayplayer()

Dim counter As Long
Dim begin As Long
Dim ending As Long
Dim cent As Long
'
Do

counter = Worksheets("DATA").[ah1].Value

begin = counter + 1
ending = counter + 781
cent = ending - 100
counter = counter + 1
Worksheets("DATA").[ah1].Value = counter

Application.ScreenUpdating = False

ActiveSheet.ChartObjects("Chart 21").Activate
ActiveChart.SeriesCollection(1).Values = "=DATA!R" &
cent & "C13:R" & ending & "C13"
ActiveChart.SeriesCollection(2).Values = "=DATA!R" &
cent & "C20:R" & ending & "C20"


ActiveSheet.ChartObjects("Chart 18").Activate
ActiveChart.SeriesCollection(1).Values = "=DATA!R" &
begin & "C17:R" & ending & "C17"
ActiveChart.SeriesCollection(2).Values = "=DATA!R" &
begin & "C24:R" & ending & "C24"

Application.ScreenUpdating = True

Loop While counter < 10000

End Sub
